Description

Technical Field

[0001] The utility model relates to the technical field of skimmers, and particularly relates to a separable cooling skimmer. Background Art

[0002] In the production process of an ironmaking blast furnace, as a key device for the front-of-furnace operation, the skimmer undertakes the important task of effectively separating molten iron from molten slag. However, the design of traditional skimmers often has limitations such as fixed structure and large size. These characteristics not only increase the manufacturing and installation difficulties of the skimmer, but also pose higher requirements for its baking preparation process. Since the skimmer is directly exposed to a high-temperature and high-scouring environment, its service life is often much lower than that of the main trough of the blast furnace, which leads to frequent replacement requirements and thus has an adverse impact on the normal production operation of the blast furnace;

[0003] When the skimmer needs to be replaced when its service life expires, since the skimmer needs to perform slag blocking operation, the main trough often needs to be temporarily stopped from being used. This not only interrupts the continuous tapping operation of the blast furnace, but also may have an adverse impact on the furnace condition and temperature control of the blast furnace. In addition, due to the large volume of the skimmer, its replacement process is complex and time-consuming, further exacerbating the instability and uncertainty of blast furnace production.

[0004] Therefore, a separable cooling skimmer is needed to overcome the occurrence of the above problems. Summary of the Utility Model

[0005] In order to solve the above problems, the embodiment of the utility model provides a separable cooling skimmer, achieving the purpose of solving the problems raised in the background art.

[0006] The embodiment of the utility model specifically adopts the following technical solutions to achieve the above purpose: A separable cooling skimmer, comprising a frame clamped on the main trough, a slag blocking plate for preliminary slag blocking is arranged on one side of the frame, a skimming block for secondary slag blocking is clamped inside the frame, and a cooling plate for cooling the skimming block is arranged inside the skimming block.

[0007] As a further improvement of the above technical solution:

[0008] A clamping groove is opened inside the main trough, and the frame is arranged inside the clamping groove.

[0009] A cavity for accommodating the slag blocking plate is arranged between the frame and the clamping groove.

[0010] An inclined groove one is arranged on the side of the slag blocking plate close to the frame, and an inclined groove two is arranged on the side of the frame close to the slag blocking plate.

[0011] A wedge-shaped groove for accommodating the skimming block is arranged inside the frame.

[0012] A groove for accommodating a cooling plate is formed inside the slag skimming block.

[0013] Lifting rings are fixedly connected to the top of the slag baffle, the top of the slag skimming block, and the top of the cooling plate.

[0014] The beneficial effects of the embodiments of the present utility model are as follows:

[0015] During actual use, when the slag skimmer needs to be replaced, it is mainly necessary to replace the slag baffle and the slag skimming block; firstly, the volumes of the slag baffle and the slag skimming block are smaller than those of traditional slag skimmers, which is convenient for replacement; at the same time, since both the slag baffle and the slag skimming block can perform slag blocking operations, when one of the slag baffle and the slag skimming block is replaced, the normal slag blocking operation of the slag skimmer will not be affected.

[0020] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0021] See Figures 1 to 3 , the embodiments of the present utility model disclose a separable cooling slag skimmer, including a frame 1 clamped on the main trough 2, a slag baffle 3 for preliminary slag blocking is arranged on one side of the frame 1, a slag skimming block 4 for secondary slag blocking is clamped inside the frame 1, and a cooling plate 5 for cooling the slag skimming block 4 is arranged inside the slag skimming block 4;

[0022] During actual use, when the slag skimmer needs to be replaced, it is mainly necessary to replace the slag baffle 3 and the slag skimming block 4; firstly, the volumes of the slag baffle 3 and the slag skimming block 4 are smaller than those of traditional slag skimmers, which is convenient for replacement; at the same time, since both the slag baffle 3 and the slag skimming block 4 can perform slag blocking operations, when one of the slag baffle 3 and the slag skimming block 4 is replaced, the normal slag blocking operation of the slag skimmer will not be affected;

[0023] The severely damaged part of the skimmer is the iron-facing surface, that is, the surface facing the direction of the iron flow. This part has to withstand the physical scouring and chemical erosion of the slag-iron mixed flow. The slag baffle 3 can resist the erosion of this part, and at the same time, the slag baffle 3 can be replaced separately. As the groove of the main trough 2 expands and the slag-iron liquid level drops, the skimming block 4 can achieve secondary slag blocking and can also be replaced separately when it is severely eroded. The cooling plate 5 inside the skimming block 4 is at the most central part, which is safe and reliable. By cooling, the reaction temperature at the erosion interface of the skimming block 4 is reduced, and the reaction activity is decreased, which means that the erosion rate of the skimming block 4 drops, thereby prolonging the service life; the cooling plate 5 is a water-cooled plate, which belongs to a mature technology, so the specific structure of the cooling plate 5 will not be described further.

[0024] As a further description of the present application:

[0025] A clamping groove 6 is formed inside the main trough 2, and the frame 1 is arranged inside the clamping groove 6. When installing the frame 1 on the main trough 2, only need to snap the frame 1 into the clamping groove 6, and the installation is relatively convenient.

[0028] As a further description of the present application:

[0029] A first inclined groove 8 is arranged on one side of the slag baffle 3 close to the frame 1, and a second inclined groove 9 is arranged on one side of the frame 1 close to the slag baffle 3; through the first inclined groove 8 and the second inclined groove 9, it is convenient to place the slag baffle 3 into the cavity 7.

[0030] As a further description of the present application:

[0032] As a further description of the present application:

[0033] A groove 11 for accommodating the cooling plate 5 is formed inside the skimming block 4, and the cooling plate 5 can be installed inside the groove 11. When replacing the skimming block 4, the cooling plate 5 can be taken out without replacing the cooling plate 5.
